When 2-pentene reacts with HBr, what will be the major product?
If we consider the first step (formation of carbocation by the attack of the proton).
A couple of textbooks I referred say that when the substituents on the $\ce{C=C}$ are different, the direction of ...

Confusions about inductive effect and acid strength
If one of the hydrogens in the alkyl side chain of ethanoic acid is replaced with an atom of Chlorine, the acid has a larger Ka value. My book says this is since the Cl "borrows" electron density from ...

Which of the 2 structures is more stable?
As far as I know, alkenes with more number of hyperconjugating structures are more stable. Hyperconjugation has a greater stablizing effect than Inductive effect. So, (d) should be more stable as it ...

Does hyperconjugation into sigma-star explain methylamine's increased basicity relative to ammonia?
The inductive effect with the polarisation of the C-N bond obviously plays a role in stabilising the positive charge of the conjugate acid. But given the similar electronegativities for C and H, CH3 ...

Why is C2H5 a stronger +I group than CH3?
While reading about the basic character of amines, I came across a note which said that $\ce{CH3-CH2-NH2}$ was more stable than $\ce{CH3-NH2}$ as $\ce{C2H5}$ was a stronger +I group than $\ce{CH3}$.
